         5 . The UE of  claim 1 , wherein the capability information indicates wakeup delays associated with respective modes from the one or more sleep modes or the one or more wakeup modes. 
     
     
         6 . The UE of  claim 1 , wherein the one or more sleep modes are associated with respective power consumption levels. 
     
     
         7 . The UE of  claim 1 , wherein one or more modes, from the one or more sleep modes and the one or more wakeup modes, are associated with respective wakeup delays associated with the main radio. 
     
     
         8 . The UE of  claim 1 , wherein the configuration information indicates one or more configured sleep modes based on the capability information. 
     
     
         9 . The UE of  claim 8 , wherein the one or more processors are further configured to cause the UE to:
 receive, from the network node and via a low-power radio of the UE, a wakeup signal indicating a sleep mode, from the one or more configured sleep modes, to be used by the UE for the wakeup procedure.   
     
     
         10 . A method of wireless communication performed by a user equipment (UE), comprising:
 transmitting, to a network node, capability information for a wakeup procedure associated with a main radio of the UE, the capability information being associated with at least one of one or more sleep modes supported by the UE or one or more wakeup modes supported by the UE; and   receiving, from the network node, configuration information for the wakeup procedure, the configuration information being based on the capability information.   
     
     
         11 . The method of  claim 10 , further comprising:
 receiving, via a low-power radio of the UE, a wakeup signal indicating that a downlink control channel is to be monitored by the UE via the main radio,
 wherein receiving the wakeup signal is in accordance with the configuration information, and 
 wherein the wakeup signal is received while the main radio is in a sleep mode of the one or more sleep modes; and 
   monitoring, via the main radio and based on receiving the wakeup signal, the downlink control channel in accordance with the configuration information.   
     
     
         12 . The method of  claim 10 , wherein the configuration information indicates one or more wakeup signal monitoring occasions associated with respective configured sleep modes. 
     
     
         13 . The method of  claim 12 , further comprising:
 receiving, via a wakeup signal monitoring occasion of the one or more wakeup signal monitoring occasions, a wakeup signal; and   performing the wakeup procedure using a configured sleep mode that is associated with the wakeup signal monitoring occasion as indicated by the configuration information.   
     
     
         14 . The method of  claim 10 , wherein the configuration information indicates one or more wakeup signal monitoring occasions associated with respective configured wakeup modes. 
     
     
         15 . The method of  claim 14 , further comprising:
 receiving, via a wakeup signal monitoring occasion of the one or more wakeup signal monitoring occasions, a wakeup signal; and   performing the wakeup procedure using a configured wakeup mode that is associated with the wakeup signal monitoring occasion as indicated by the configuration information.   
     
     
         16 . The method of  claim 10 , further comprising:
 receiving, via a low-power radio of the UE, a wakeup signal indicating a wakeup delay; and   performing the wakeup procedure using a configured wakeup mode or a configured sleep mode corresponding to the wakeup delay as indicated by the configuration information.   
     
     
         17 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
